block: Unhash also block device inode for the whole device
BugLink: http://bugs.launchpad.net/bugs/1659111
Iteration over partitions in del_gendisk() omits part0. Add
bdev_unhash_inode() call for the whole device. Otherwise if the device
number gets reused, bdev inode will be still associated with the old
(stale) bdi.
